TITLE: Lock-In Electronics

Requesting Laboratory / Division / Group:

Communications Technology Laboratory Radio Frequency Technology Division RFTD HQ Group (672.00)

General Statement of Need:

The requested digital lock-in amplifier system shall provide high-sensitivity phase-sensitive detection and real-time digital signal processing to support electro-optic sampling (EOS), carrier-envelope-offset (fCEO) detection, frequency-comb stabilization, and traceable waveform metrology applications. The system shall support demodulation and measurement of low-level optical and electrical signals with high dynamic reserve, low noise, and stable phase detection over a frequency range extending to at least tens of megahertz. The instrument shall include multiple simultaneous demodulators, integrated proportional-integral-derivative (PID) controllers, synchronized data acquisition, and advanced digital filtering capabilities to enable closed-loop laser stabilization, optical frequency referencing, and precision measurement of ultrafast electrical and optical waveforms. The system shall provide flexible external triggering, high-speed data streaming, and software interfaces compatible with automated laboratory control and long-term measurement operation. The lock-in amplifier is required to support development of SI-traceable electro-optic waveform measurements, frequency-comb-based metrology, optical-to-electrical signal characterization, and advanced feedback control architectures used in ultrafast photonics and timing applications.
